Question / Help Encoding overloaded!

[CaptainBiplane]

I would love to see the new amd encoder (past update 18.0) fixed - the encoder before update 19.0 worked perfectly, when I updated to 19.0, it just went overloaded and the stream was an unwatchable slideshow, I have a suspicion that obs can't use more than a set amount / % of the cpu and I won't update until this is fixed. The problem is in every update from 19.0.

Please post a log - https://obsproject.com/forum/threads/please-post-a-log-with-your-issue-heres-how.23074/

No way to determine if this is a bug without more info.

I think I am also having a problem either with the new version of OBS (20.1.1) or the new AMD drivers (17.11.1).
Recording with the AMD H.264 encoder has become very choppy and OBS says it's being overloaded. It's never said that before.
I'm leaning towards a driver issue because I have another recording program I use that also is now producing choppy recordings.
Anyway, I have a log file for a test recording I just did with the 17.11.1 drivers.
I also rolled back to 17.7.2 drivers to see what would happen. The recording was normal and OBS no longer told me it was overloaded.

I need the new drivers for AC Origins though, so I've resorted to using my other recording software to record in avi till something gets fixed.

Here is the log file (by the way - it doesn't have any problems with a 720p60 stream, only at 1080p60, but the cpu usage is fine - around 2% - 4% and it doesnt matter what settings I play around with, each time its just a slide show at 1080p60)

@CaptainBiplane Could you start by running through the steps for a clean driver install and testing afterwards?

I should have mentioned it, but ive tried doing that aswell using DDU and at least 4 different video drivers, there was no difference between the newest and the older ''more stable'' ones.

Edit: ive even tried flashing a different bios ( from rx 480 to rx 580 bios) and still the same thing happened

 

[Sapiens]

I assume one of the four packages you tried was the latest release?

 

[CaptainBiplane]

Yeah the latest - 17.11.1 and each time a new driver comes out, I do a clean install, don't think theres a problem with the video drivers

 

[Sapiens]

Are you using advanced output mode in OBS? If so, could you test with one of the simple output quality presets and see if that works any better?

 

[CaptainBiplane]

Same thing

 

[CaptainBiplane]

Just a note - I only use the Quality encoder preset as the Balanced and Speed presets look so bad that I might aswell stream at 720p

I tried Simple Mode with the "Indistinguishable" preset. It was even worse than my custom settings. It was overloaded right when I started recording. With my custom settings, it only got overloaded when I was in a certain area in the game.

And if you switch to the x264 low cpu use encoder?

Yeah same here, but those presets use a different rate control something like minimum and maximum QP insted of bitrate and i have no idea what it is so i just use CBR

My cpu is an fx 8350, it only goes up to a 1080p 30fps in a x264 stream and even then its a pretty heavy performance hit in games so my only option is a gpu encoder

@CaptainBiplane
QP is kind of like VBR but done in a different way. For streaming though, you need CBR from what I've read. I don't do streaming.

As for x264 encoding, same result with the "Indistinguishable" preset.

Just to be safe I rolled back the video drivers again today to 17.2.1 and it was identical - v18 worked perfectly and the newest release didn't. I'm still saving up to get a good enough cpu for x264 or buy a 1070 for NVENC encoding
